Protein-free natural rubber, latex thereof, and method for manufacturing said rubber and latex |
摘要 |
Provided is a protein-free natural rubber for which the risk of inducing allergic reactions is extremely low. Also provided are a latex of said rubber and a method for efficiently manufacturing said rubber and latex. In the provided manufacturing method, a urea compound, a surfactant, and a polar organic solvent are added to a natural rubber latex, and the proteins in said latex are denatured and then removed. This results in a protein-free rubber latex having a nitrogen content of at most 0.001% as measured by an RRIM test. Also, the amount of protein in a solid rubber obtained by drying the provided natural rubber latex is at most 0.5 mug/g as measured by an improved Lowry method.
